New Zealand Prime Minister Jacinda Ardern promised the money last the month after restating the offer to resettle 150 refugees from Australian offshore detention.

Deputy secretary Jeff Langley from the Ministry of Foreign Affairs and Trade said there are a number of different ways the money could be channelled including to the Red Cross and other NGOs operating on the island.

He said the ministry is also talking to the Papua New Guinea government to identify needs created by the refugee population on the island.

The skilful fly-half joins All Blacks great Richie McCaw as the only player to have retained the award, while Barrett, McCaw and the great Dan Carter are the only three to have won the prize more than once.
